Jeremiah P. Ostriker has been an influential
researcher in one of the most
exciting areas of modern science, theoretical
astrophysics,
with current primary work in the area of cosmology, particularly
the aspects that can be approached best by large scale
numerical
calculations.

Ostriker has investigated
many areas of research, including
the structure and oscillations
of rotating stars, the stability
of galaxies, the evolution
of globular clusters and other
star systems, pulsars, X-ray
binary stars, the dynamics
of clusters of galaxies, gravitational
lensing, astrophysical
blast waves, active
galactic nuclei, the cosmic web, and galaxy formation.

Most significantly, Ostriker's
research
focused on the theories of
:

Dark
Matter and Dark
Energy

The
Warm-Hot Intergalactic
Medium (WHIM)

Galaxy Formation and black hole growth

Interaction between Quasars and their surroundings

Ostriker has supervised and
collaborated with many young
researchers and graduate students.
He is the author or co-author
of more than 500 scientific
publications.
